I've got my GE 6-zone QS integrated with my setup now. A few things I learned might be helpful to others:
1) the IR input port polarity *does* seem to matter for me. At one point during my setup debug, I had the mini-plug to GE polarity reversed ('comm' connected to the tip of the miniplug rather than the sheath). At that point, the GE control didn't work. When I reversed the polarity, it did, nothing else changing.
The polarity that worked for me (connecting to my Buffalo IR block via mono-mini-plug) was IR-Data to the mini-plug tip, IR-Comm to the mini-plug sheath.
This makes sense (mini-plug sheath is typically 'ground'), but seems to contradict what somebody above heard from Lutron support (that polarity didn't matter). YMMV.
2) When I first connected my GE to the Buffalo IR block as a flasher, all the flashers in my system (and the green LED on the block) went solid on, indicating a ground problem or major noise in the system. IR control still worked to some devices, but it was flaky. Poking around, I realized that if I touched the outer metal of my IR receiver (they 'eye'), the flashers all went off. I wasn't grounded, so it seemed like a capacitive issue.
For the heck of it, I tried running a separate ground wire (from a nearby receptacle on the same circuit as the IR repeater, different circuit from the GE) to the outer case of my IR receiver eye. It worked. All the flashers went off, and my IR control works fine for everything.
When in doubt, try playing with grounds.
3) I got my Harmony remote programmed up. The advice above worked:
- pick the activity you are interested in
- go to 'customize buttons'
- click 'add a sequence'
- create a sequence labeled 'play'
- - add step 'lights' -> 'scene 2'
- - add step 'PS3' -> 'play'
- Assign the 'play' button to the 'sequence' 'play'
I set it up so that 'play' triggers scene 2 (all off except dim rope lights and step lights), 'pause' triggers scene 3 (medium lights for getting around without blasting your eyes.
I also went in and added 'lights' and 'dim' as the bottom two touch screen buttons in each of the activities.
When I tried it out, I realized two things:
1) I need to add 'scene 3' to the STOP button as well, and
2) When I'm done with a movie or cable, I typically just hit the Harmony 'power off' button, which turns off the ps3/rs20/receiver. This was leaving the lights off.
So, I went back and added a stop sequence just like play and pause.
I also went into each of my activities, found the 'when you leave this activity' section, and added a 'lights' -> 'scene 3' command. If I power down, lights should now come up.
Minor problem, if I switch from one activity (DVD) to another (Cable), the lights will come up. Since I have a 'dim' touch screen button on the front page of each activity, this is only a minor inconvenience.
Hope this saves somebody else a bit of debugging. I spent about four frustrating hours yesterday debugging the polarity/noise issue...
